1' 0 all whmm it nm/y concern:

Be it known thatwe, Jonas LANG, a citizen of France, and Auous'r Fisonnn, a citizen of the United States of America, residents of Chicago, in the county of (look and State of Illinois, have invented certain new and useful improvements in Vehicle-Tires, of which the following is a specification.

The main object of this invention is to )I0'- vide an improved form of resilient hollow cushion-tire particularly adapted for heavy vehicles and of such structure as to be unafl'ected in its resilience by punctures of its tread-surface. We accomplish this object by the device shown in the accompanying drawings, in whic Figure 1 is a transverse section of a vehicle tire constructed according to our invention. Fig. 2 is a fragmentary longitudinal section of the same on the line 2 2 of Fig. 1. Fig. 3 is a side elevation of the complete tire on a reduced scale. Fig. 4 is a transverse section of the same tirc, showing the approximate effect of load on the same.

in the construction shown in the drawings, the tire consists of an endless tube 4, having its outer walls constructed of alternate layers of rubber 5 and canvas 6. The wall of the tube at 8 alon the treadsuriace of the tire is. of considerab y greater thickness than the opposite wall 9, which engages the rim 1001 the wheel. Only the sim lest form of wheelrim and rim-surfaced tl ie tire is shown, as the main feature of this invention is the internal structure of the tire.

The hollow interior of the tire is subdivided into two principal divisions by means of the annular partition 7, which extends lon itudinally of the tube and transversely o the plane of the wheel. The wall of the tube on the rim side of the tire is supported by a cen tral annular web 11, extending between the partition 7 and said wall at right angles to the partition or in the plane of the wheel. The wall of the tube which forms thctread ol' the wheel is supported by two annular webs 12, which lie in parallel relation with the plane of the wheel and extend between the partition 7 and the Wall 8 of the tube. The webs l2 meet the partition 7 alonglincs lying interinediately between the web 1] and the sides oi?the tube. The annular spaces inclosed andseparated from each other by the said partition, webs, and the walls of the tube are preferably again sulnlivided by radiallyplanes and nicotin the disposed webs 13 to give the tire a cellular structure. As in the case of the longitudinal webs, the radial webs 13, which lie between the partition 7 and the tread of the wall, meet the partition 7 at points intermediate 01 the webs 13, which lie between the partition 7 and the rim-surface of the tire}. The radial webs 13 are preferably of considerably less a thickness than the longitudinal webs, as the former are intended more to form subdivisions of the air-spaces than to support the tread of the tire. All of the webs and partitions are preferably of rubber or similar resilient material.

In the operation of the device shown it will be understood that the resilience of this form of tire is largely due to'the yielding of the resilient partition 7 under the action of the staggered resilient supporting-webs 11 and 12 and is also assisted'by the air confined in the inclosed spaces. In casethe tire is punctured the effect of the puncture is confined to a limited space on account of the subdividing webs, and the support given to the tire by the supportin webs is so much greater than the support w ich is afiorded by the confined air that punctures will have but little efi'ect on a tire of this construction.

It will be seen that some of the details of the construction shown may be altered without departing from the spirit of our invention. 9

What we claim as our invention, and desire to secure by Letters Patent, is i 1. A vehicle-tire, comprising a tube of resilient material a longitudinal artition subdividin the interior of said tu e, and a'pluralityo longitudinal webs on each side of said partition and extending across the space be tween said partition and the o pos1,te walls of said tube, the webs on one sid tition lying in different planes from th'pse on the other side, substantially as described.

2. A vehicle-tire comprising an endless tube of resilient material, an annular partition subdividing the interior of said tube and disposed transversely of the plane of the wheel, and a plurality of annular webs lying substantiallyparallel to the plane ofithe wheel and extending between said artition and the opposite walls of the tube, t ie'webs on opposite sides of said partition 1 ingiin difierent. partition at different points, substantially as described.

3. A vehicle-tire, comprising a tube of ree of sald par- IIC silient materiel, e'longitudinel isrtitio'n subdividin the interior of said tune, and a pinralit o transverse webs on each side of mid partition and extending across the Splice between said partitions and the opposite wulls of said tube, the webs'on one side or" said pertition lying in difierent limes from those on the other side, substentinli as described.

4. A vehicle-tire eo'mprisin a tube of resilient material, s longitudinal telity of su partition an the opposite walls of sand tube,
